You must disconnect the lower gas spring (Disconnecting the Lower Gas Spring, page15) and the upper gas
spring (Disconnecting the Upper Gas Spring, page17) before disconnecting the steering system from the lower
link of the mount. Removing the steering system without disconnecting the gas springs creates a situation in
which, if the latch is accidentally released, the lower link of the mount will move suddenly with great force,
potentially leading to severe injury.
CAUTION
The lower pin is the final piece connecting the steering system to the mount. When you remove the pin, the
steering system and the drive motor and shaft, if they are still installed, may fall causing personal injury or
damage to the motor. Make sure that you support the weight of the steering system before you remove the pin.
To avoid personal injury or damage to the motor, this procedure should be performed with two people.
1 Remove the pull handle from the cable (Removing the Pull Cable Handle, page9).

Service Procedures 61
Removing the Steering Servo Motor and Shaft Carrier
Before you can remove the steering servo motor, you must open the steering system housing (Opening the
Steering System Housing, page60).
1 Support the top of the steering system housing on the edge of a bench or a table and not on the top of the
shaft carrier.
NOTICE
The steering servo motor bracket is the main component holding the steering assembly together. If you set the
assembly on a table so that the shaft carrier bears the weight of the assembly, the top of the steering system
housing may suddenly fall down, shifting the assembly components and potentially causing product damage.
Do not clamp the edge of the housing to a bench or table to support it. Clamping may damage the coating or
bend the housing.
